- Tier
live· T1a-live-tsoThe transmission system operator publishes an hourly series, and the calibration rate comes from the same jurisdiction.
Live TSO feed, own-jurisdiction rate (±2σ from 5-yr backfill, fallback ±15%)
- Uncertainty
- ±15% of peak GW
Regions with a five-year backfill archive use ±2σ of observed annual variance instead of this default fraction.
Published envelope for this tier. See the uncertainty model.
- Source provenance
verified· Verified upstream linkThe snapshot value comes from a verified upstream feed or anchor.
- Source
- EIA NYISO wind (Zones D+E share, ~75% of statewide curtailment)

Tier, provenance, and source are read at build time from src/lib/regions.ts — the same table the globe draws from. The validation record below is generated separately and gated against it by npm run ci:docs-drift.

Discrepancy analysis
No backfill and no TSO anchor. Region relies solely on the live snapshot; nothing to triangulate against.
Known limitations
No region-specific limitations recorded. See docs/methodology/historical-backfill.md §"Known limitations" for cross-cutting notes.
